Adjoining landowners are owners of land with common boundaries, and have mutual rights, duties, and obligations related to their adjoining pieces of land.
In California, adjoining landowners, also known as contiguous property owners, have rights and responsibilities that are governed by state law. These include the duty to maintain property boundaries and fences, the right to trim branches and roots that encroach onto their property from a neighbor's tree, and the obligation to not cause harm or damage to the neighboring property. California Civil Code sections 841 to 848 specifically address issues related to shared fences and boundaries, outlining that neighbors are equally responsible for the construction, maintenance, and costs of these fences unless an agreement states otherwise. Additionally, the law provides for easements, which may grant a neighbor the right to use a portion of another's land for a specific purpose, such as access to a road. Disputes between adjoining landowners are common and can often be resolved through negotiation, mediation, or, if necessary, litigation.
